There are too many unknowns to be able to really help. Some things to start with:

1. What web server as you using? You need something installed locally to serve your game.
2. Does Phaser even load? Is the whole page black, or just the canvas? Try adding some HTML onto the page, does it appear?
3. How are you opening your game? You should be going to a URL on your local server.
